PersistentEvidenceStore

hotmint_storage::evidence_store

Struct PersistentEvidenceStore 

Source 
pub struct PersistentEvidenceStore { /* private fields */ }
Expand description

Persistent evidence store backed by vsdb.

Proofs survive node restarts. Uses a MapxOrd<u64, EquivocationProof> for the proof list (keyed by auto-increment ID) and a MapxOrd<u64, u8> as a committed-set (keyed by a hash of (view, validator)).

Implementations§

Source§

impl PersistentEvidenceStore

Source

pub fn open(data_dir: &Path) -> Result<Self>

Open an existing store or create a new one. Must be called after vsdb::vsdb_set_base_dir.
